Detailed Description
In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.
As shown in fig. 1, the lower roll replacing hanger of the roll coater of the present invention comprises a hanger beam 100, a lifting rope 200 and a hanging scaffold 300, wherein the hanger beam 100 is a long h-beam, the lifting rope 200 is respectively connected to the ends of the two ends of the hanger beam 100, and the lifting rope 200 is a steel rope with high strength. In the utility model, the hanging tool is connected and fixed with the lower rollers of the lower coating roller and the lower material picking roller of the roller coater through the hanging scaffold 300, and because the lower coating roller and the lower material picking roller of the roller coater are arranged on the frame of the roller coater, one end of the lower coating roller and the lower material picking roller is connected with the frame of the roller coater through the shaft coupling and the shaft coupling shaft head flange, the hanging scaffold 300 is not convenient to be connected at the end, therefore, the utility model discloses only need to adopt one hanging scaffold 300, connect one hanging scaffold 300 at the end of one of the hanging ropes 200, through the connection of the hanging scaffold 300 and the shaft end fixing shaft bearing plate of the lower roller of the roller coater, the other hanging rope 200 is hung on the shaft coupling shaft head flange at the other end of the lower roller; during lifting, the lower roller can be lifted away from the rack of the roller coater by directly lifting the lifting beam 100 by using a crown block.
As shown in fig. 2, the hanging scaffold 300 of the present invention comprises a limiting disc 320, a connecting disc 330 and a connecting shaft 340, wherein the limiting disc 320 and the connecting disc 330 are both disc structures, the limiting disc 320 and the connecting disc 330 are respectively welded and fixed at two ends of the connecting shaft 340, and the limiting disc 320, the connecting disc 330 and the connecting shaft 340 form a structure with an "i" shaped longitudinal section; set up lower roll connecting hole 310 on connection pad 330, the position of lower roll connecting hole 310 is corresponding with original mounting hole on the axle head fixed axle bearing plate of roller coat machine lower roll, when connecting platform 300 and roller coat machine lower roll, directly utilize the bolt pass lower roll connecting hole 310 with corresponding mounting hole after through nut locking can, the dismouting is very convenient to utilized the original structure of lower roll, need not increase other connection structure. Because original mounting hole is two at least on the axle head fixed axle bearing plate of roller coat machine lower roll, the utility model discloses the quantity of the lower roll connecting hole 310 on well platform sling 300 should also be unanimous with the mounting hole, and the position of lower roll connecting hole 310 should also be with the mounting hole one-to-one, therefore lower roll connecting hole 310 should be annular equipartition on connection pad 330.
